A heterozygous tall yellow plant is crossed with a homozygous short green. What will be the genotypes 3. and phenotypes, and probabilities of the first generation? Genotype of the heterozygous tall, yellow plant Genotype of the homozygous short, green plant Genotypes Phenotypes Right handedness (R) is dominant over left (r) Browyn eves (B) are dominant over blue (b). A man who is blue eyed and right handed, whose father was left handed, married a left handed woman with brown eyes, whose mother was blue eyed. What are the possible phenotypes and genotypes of the offspring and the probability for each? 4. Genotype of the man Genotype of the woman Genotypes Phenotypes What is the probability of getting right handed offspring? What is the probability of getting blue eyed offspring? What is the probability of getting offspring heterozygous for both traits? What is the probability of getting offspring that are homozygous dominant?

5. If flower color shows codominance, and R = red and r = white, what will the %3D %3D offspring of a cross between RR x rr look like? * 100% red 75% red, 25% white 100% red and white 100% pink 25% red, 50% red and white, 25% white
2. A trait in garden peas involves the curling of leaves. A dihybrid cross was made involving a plant with yellow pods and curling leaves to a wild-type plant with green pods and normal leaves. All F1 offspring had green pods and normal leaves. The F1 plants were then crossed to plants with yellow pods and curling leaves. The following results were obtained: 117 green pods, normal leaves 115 yellow pods, curling leaves 78 green pods, curling leaves 80 yellow pods, normal leaves A. Conduct a chi square analysis to determine if these two genes are linked. B. If they are linked, calculate the map distance between the two genes. How accurate do you think this distance is?
13. In another species of berry, Rass berrylis, the allele for yellow fruit (F) is dominant to the allele for red fruit (f), and the allele for thorny stems (T) is dominant to the allele for thornless stems (t). The gene for fruit colour is 17.4 map units from the stem thorniness. gene for a. Draw a Punnett square to illustrate the cross between a Rass b. with red berries and thornless stems and a plant that was heterozygous for both characteristics. (The parents of the heterozygous plant were yellow-fruiting and thorny, and red- fruiting and thornless, and were homozygous for both traits.)
16. In Jimpson weed, the alleles encoding purple and white flower color display incomplete dominance. Heterozygous plants have mauve-colored flowers. If two mauve-flowered plants are crossed, what is the expected phenotypic ratio of the F₁ generation?
